Material；
Step b, the obtained mixture of step a is put into high speed zipper extruder, and will mixed under stirring conditions
It closes material and is fused into molten condition, obtain melting charge；
Step c, melting charge is subjected to blowout Zipper forming by high speed zipper extruder, obtains film zipper；
Step d, the film zipper that step c is obtained is cooled down, film zipper is carried out shaping；
Step e, the film zipper after step d sizing zipper bag making process is transferred to carry out earnestly, to carry out sideline judge's heat-sealing,
Obtain product.
Preferably, the heating component of high speed zipper extruder described in step b includes four barrels and gets to know, and it is heated
Temperature is respectively one 160 ° of barrel, 2 165 ° of barrel, 3 170 ° of barrel, 4 175 ° of barrel and gets to know 180 °.
Preferably, 10 hours a length of when film zipper described in step d is cooling, keep the sizing of film zipper complete.
Compared with prior art, the beneficial effects of the present invention are:
(1) present invention is using low density polyethylene 4025AS as main material, and adds low density polyethylene (LDPE) LLDPE218W
It is auxiliary material with medium density polyethylene MDPE, carries out being mixed and made into film zipper according to the component ratio of 8:1:1, there is film zipper
The advantages that high rigidity is anti-bending, anti-fracture, and heat sealer is high, infiltration is good, solves film zipper hardness currently on the market
It is low, often bending be easy to happen fracture, while the problem of infiltration difference, realize that the film zipper has more practicability, more added with
Conducive to the use of film.
(2) production technology of the present invention is reasonable, and process is succinct, and high-efficient, reduces the production cost of film zipper, simultaneously
Reduce the pollution to environment, be advantageously implemented in production process and be more energy-saving and environmentally friendly, increases productivity effect.
